I don't have a link to share but an Owen Brands in NJ just posted an ad for " 1967 Ford shelby intake" and it appears to be the intake and carb for $3800. Maybe someone here is interested if they confirm authenticity and negotiate. I'm not affiliated with it and don't need it just figured I'd share as it's not something I see every day on Facebook marketplace.
